python-pybind was not the right approach and is in failure since
it's been upgraded to V2.6.1.

Building with setup.py now requires a cmake build first.
With this new approach we can build the package with cmake 
for python bindings in C++ AND we also have the 
C++ bindings in python as an option (depending & requiring the first one).

I make this a host-only package, in the sense that other packages will
require it at build time, and I don't forsee any reasons to have
such a package as a target package.
